WINDOW.

Specification of Letters Patent.

Patented Nov. 17, 1914.

Application filed February 6, 1914. Serial No. 816,973.

To all who-m it may concern:

Be it known that I, Donsn'r'r A. DA-v1soN, a citizen of the UnitedStates, residing at Richmond, in the County of Henrico, State ofVirginia, have invented certain new and useful Improvements in Windows;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to certain novel and useful improvements inwindows, and has particular application to that class of windows whereina sash or sashes may be swung from a substantially vertical to asubstantially horizontal position, or vice versa, to regulate the amountof ventilation, to permit ready, convenient and safe access to the glassfor cleaning, and for other purposes.

In the present instance I propose to provide a structure whereina sashor sashes, may be readily manipulated to swing the same to a selectedangle for any desired purpose, and furthermore, I provide means wherebythe sash may be automatically held or fastened at a desired inclinationrelative to the window frame.

v Still a further object .of my invention is the provision of deviceswhereby, the liability of displacement or' injuries to the working partsof the window, under the stress of sudden ars, such' as would be due togusts ofwind and the like, is avoided.

I also aim' to provide a window of this class-which will embody in itsconstruction the desired features of simplicity,.efiiciency andconvenience.

lVith the above recited objects and others of a similar nature in view,my invention consists in the construction, combination and arrangementof parts set forth in and falling within the scope of the appendedclaims.

In the accompanying drawings: Figure 1 is a perspective view of a windowembodying my invention, the sashes being shown as swung inward to ahorizontal position. Fig. 2 is a view partly in elevation and partly invertical section, and showing the sashe's as slightly swung or tilted.Fig. 3 is a hori-.

zontal cross sectional view taken through a portion of the window frameand showing the position of the side bars of the upper and lower sasheswhen the windows are in vertical position, this view also illustratingthe position of the sliding follower plates relative to the metallicguide strips of thewindow frame. Fig. 4 is a view similar to Fig. 3,showing but one of the sashes and the adjacent portion of the windowframe, and illustrating the sash as slightly tilted. Fig. 5 is ahorizontal cross sectional view taken on-line 55 of Fig. 2. Fig. 6 is asimilar view of Fig. 5, but showing the sash in its vertical ornon-tilted position. Fig. 7 is a detail perspective view.of one of thefollower plates. F ig; 8 is a similar view of one of the hinge platesofthe sash. Fig. 9 is a perspective view of the bottom portion of one ofthe side bars of the sash and showing the same in substantiallyhorizontal position when open to its greatest extent, this viewillustrating the manner in'which the shouldered end of the flange 8bears against the adjacent flange of the frame strip 4: to preventfurther downward movement of the sash.

Before entering into a detailed description of my invention, I willbriefly describe the construction of the preferred form of my inventionillustrated herein, and as the de-' vices for one sliding and swingingsash are similar in constructionto the devices of the other sash, adescription of one will suffice for both. 7

'It will be noted that I have arranged at opposite sides of the windowframe, me-

. tallic guide strips which extend the entire length of the frame. Eachof thesestrips is provided with oppositely disposed, outwardly turnedflanges. To the outer face of each side bar of the window sash I fastena strip, one of the longitudinal edges of which is provided with an outturned flange. Sliding upon each guide strip of the window frame is apivot plate having a pivot pin, and this pin is embedded in and engagesthe lower portion of the adjacent side bar of the sash. Also slidingupon each guide strip of the window frame is a follower plate, to whichis attached one end of one of the sash cords of the window. This platehas also pivotally connected therewith one end of a'link bar, theopposite end of said link bar being pivoted to the adjacent side bar ofthe sash. The pivot plates at the lower ends of the sash are formed withapertures 24, as shown in Fig. 8 which when the window is verticallydisposed receive the locking stud 25 on the adjacent side bar of "thesash and hold the window closed, the grip or pressure of these studsagainst the plate being also sufiicient to hold the latter in tiltedposition, so that it requires a positive effort to change theinclination'of the window sash. Fur thermore, each of the slidingfollower plates is provided with tongues which are ordinarily out ofcontact with the adjacent side wall of the guide strip of the window, onwhich such follower plates slide, but when the window is jarred orshaken suddenly, as by a gust of wind, these tongues will strike againstthe adjacent wall of the window frame strip and act as a break or stop,thereby reducing the liability of the window glass being broken.

Referring to the drawings in detail the letter A indicates the windowframeas an entirety, at each vertical side of'which is a parting head 1and the sash stops 2- forming vertical grooves 3. Extendinglongitudinally the entire length of each groove and fastened to thebottom wall thereof is a metallic guide strip 4: which is approximatelyU-shaped in cross section and is provided with out-turned flanges 5 atthe longitudinal edges thereof. In-the present instance the upper sashof the window is designated by the letter 'U, and the lower sash by theletter L, and as the construction and arrangement of the devices foreach window sash is the same, a description of one will apply to both.Each window sash is provided with the usual sidebars 6, and to the outerface of each side bar I fasten a metallic strip 7 having an out-turnedflange 8 extending along one longitudinal edge thereof. Each flange iscut or broken away near the top of the sash as at 9, for the purpose ofaccommodating the follower plate 10, when the window is in its closed orvertical position sothat a weather-tight joint is at all times formedbetween the window frame and the sash. There are, of course, twofollower plates for each sash, these follower plates being at oppositesides of the window frame, andsliding upon the adjacent strips 4; Theconstruction of each follower plate is shown in detail in Fig. 7, and aswill be seen, comprises a flat or plate-like body portion having thevertical in-turned flanges 11 at opposite sides, which flanges engageand ride upon the out-turned flanges 5 of the window frame strip 4. Theplate is provided with a short top arm 12 which is off-set from theplate as at 13, this arm 12 having an eye 14 to which is attached oneend of the sash cord 15. The plate is also formed with a lower arm 16having an eye 17 adapted to receive the pivot 18 which connects theupper end of the link bar 19 with the arm 16,

the lower end of this link bar 19 being piv oted as at 20 to theadjacent side of the sash at approximately the center of the latter.Sliding upon each of the window frame strips 4, below the follower plate10, is a pivot plate 21, each of these pivot plates having theoppositely disposed vertical inturned flanges 22 which ride upon theflanges 5 of the window frame strips. Each of these plates 21 carries apivot pin 23 which extends through the bottom portion of the adjacentmetallic strip 7 of the sash and into the lower portion of the adjacentside bar of the sash. In other words, the sash is pivotally mounted atthe bottom portion thereof upon the pivots 23 carried by the pivotplates .21, so that such sash may swing from a vertical to a horizontalposition, and vice versa, upon these pivots As will be seen by referenceto Figs. 5

' the window is in its vertical position, and

the sash is therefore, locked against displacement or swinging. When,however, a pull is given to the sash to swing or tilt the same, thestuds orprojections 25 will be forced out of the aperture 24 and willbear against the adjacent surface of the plate 21, and bind to a certainextent, as shown in Fig. 5, so that the window will be maintained at atilted position when the pull or pressure upon the sash is relieved.That is to say it will take a positive pressure or pull to tiltthe'sash, and when such pressure or pull is released that sash will bemaintained in whatever tilted position it may occupy, by

reason of the fact that the stud 25 is bindfrom the adjacent wall of thewindow frame strip. Now, should the window be jarred for any reason, thefollower plate is likely to be shifted slightly laterally relative tothe window frame strip upon which it slides, and immediately this takesplace the tongues will be forced against the adjacent wall of the windowframe strip, and act as a stop to prevent further lateral movement ofthe follower plate, and consequently prevent the displacement andbreaking of the window. These tongues are useful in this connectionbecause as the follower plates fit loosely on their guide strips so asto slide freely thereon, there is necessarily a certain amount oflateral or sidewise play pen proved swinging window will be readilyapparent. When the window is closed the sashes occupy the usual verticalposition, and under such conditions the link bars 19 lie parallel withthe sides of the window frame, and the follower plates 10 are posi-'tioned on the guide strips of the window frame so that they fit withinthe cutaway portions 9 of the strips fastened to the side 7 bars oftheir respective sashes. If it is desired to open the window by tiltingthe sash the sash is pulled inward, and such pulling action forces thestuds 25 of the sash bars out of the apertures 24, so that such studsbind against theside faces of the pivot plates. Therefore, when the pullupon the sash has ceased, as when it has been tilted to the desiredposition, such sash will be held in such tilted position. Of course, asthe sash is tilted inward, the follower plates 10 of such sash slidedownward upon the guide strips of the window frame, as is shown in Figs.1 and 2, the window sash itself turning with the 'g'ins 23 as itspivots. When the sash is completely closed or in its vertical position,the in-turned flanges 8 of the side bar strips 7 fit over the flanges 5of the window frame guide strips I and thereby form a water-tight joint.

Referring to Figs. 9 of the drawings, wherein I have shown one positionassumed by one of the side bars of the sash when the sash is completelyopen or thrown to a horizontal gJosition, it will. be seen that theflange that when such sash bar is swung to a horizontal position, thelug 8 'of the flange8 will abut against the edge of the adjacent flange5 of the window frame strip, and therefore such strip will act as a stopand prevent the window sash from swinging downward past or beyond thehorizontal position.

It will be noted that by reason of the di vergence of the sides of theplates 4, when the sliding members are pressed apart by the action ofthe studs before referred to, these diverging sides will tend to flattenout or spread or to further diverge, and when they thus flatten out orspread, their free edges are brought into intimate contact with thesliding plate and held with sufficient friction to positively insureagainst sliding movement of the sliding plates.

It will be noted that I have provided an exceedingly simple, yetefficient type of swinging window, embodying but relatlvely few parts,and these are so constructed that of the sash bar strip 7 near its lowerend is formed with a stop lug 8 so they are not liable to get out oforder or be easily injured.

While I have herein shown and described one particular embodiment of myinvention, I wish it to be understood that I do not confine myself toall the precise details of construction herein set forth by way ofillustration, as modification and variation may be made withoutdeparting from the spirit of the invention or exceeding the scope of theappended claims.
